Аннотация

Logical analysis of the existence notion is closely related to treating individual descriptions as the type of denoting expressions. It is impossible to construct true statements about physically nonexistent objects, about mythological and literary persons in frame of extensional theories of individual descriptions, particularly in Russell's theory. However if existence of any object is understood as known or believed existence of it, then it is easy to ascribe in epistemic modal contexts to statements in question value "truth". It is necessary to revise Russell's contextual definitions of individual descriptions under such approach and to demand fulfilling so called epistemic existence and uniqueness condition by descriptions to make them genuine singular terms.
